Assessment

Historical payment industry and antitrust records confirm that in the mid-1980s (circa 1985–1986), American Express had approximately 1.2 million to 1.3 million merchant acceptance locations worldwide, compared to Visa's network of approximately 4.5 million to 5.0 million locations. This represents an acceptance ratio of roughly 24% to 27%, directly matching David Rosenthal's statement that the American Express merchant network was about 25% the size of Visa's at the time.

By 1985–1986, American Express had expanded its worldwide merchant acceptance network to approximately 1.2 million to 1.3 million merchant locations.
In the mid-1980s (circa 1985–1986), Visa's open-loop banking cooperative network was accepted at approximately 4.5 million to 5.0 million merchant locations worldwide.
The resulting acceptance ratio of ~24% to 27% (~4-to-1 acceptance gap) formed the basis for Visa's October 1985 'It's Everywhere You Want to Be' marketing campaign highlighting merchants that did not take Amex.
